Frequently Asked Questions
What is the supply voltage range for the CD74AC573M?
The CD74AC573M operates over a wide supply voltage range of 1.5V to 5.5V, making it compatible with both 3.3V and 5V logic systems. This flexibility allows seamless integration into modern low-voltage microcontroller designs as well as legacy 5V TTL-compatible systems.
What are the key electrical specifications of the CD74AC573M?
The CD74AC573M features a maximum output low current (IOL) of 24mA, a load capacitance rating of 50pF, and belongs to the AC logic family known for high speed and noise immunity. It is housed in a 20-Pin SOIC (R-PDSO-G20) package with JESD-609 e4 moisture sensitivity classification.
What applications is the CD74AC573M suitable for?
The CD74AC573M is ideal for data bus buffering, address latching in microprocessor systems, I/O port expansion, and memory interface designs. Its 3-state outputs allow multiple devices to share a common bus, making it a common choice in embedded computing and industrial control applications.
Is the CD74AC573M compatible with TTL logic levels?
Yes, the CD74AC573M in the AC logic family is fully compatible with TTL input levels while providing CMOS-level outputs. This makes it suitable for interfacing between TTL-based legacy circuits and CMOS-based modern microcontroller or FPGA systems.
What is the difference between CD74AC573M and CD74AC373?
The CD74AC573M is described as a broadside version of the 373 (CD74AC373). The primary difference is pin layout: the 573 places all data inputs on one side and all outputs on the other side of the package, simplifying PCB routing in bus-oriented designs compared to the 373's interleaved pin arrangement.
